Paper Abstract

In our work we focused on possibility of obtaining phosphate nano-phase structures in antimony-germanate glasses doped with europium ions. The glasses with molar composition of 50(Sb2O3 - GeO2) – 50(SiO2 - Al2O3 - Na2O) doped with 0.5mol% Eu2O3 were prepared by standard melt-quenching method. In order to optimize glass-ceramic system the influence of phosphate concentration (up to 10mol%) on spectroscopic properties have been investigated. The symmetry nature of molecular structure around europium ions have been determined from the intensity ratio between (5D07F2)/(5D07F1) transitions. The effect of prominent Stark splitting of luminescence band at 612 nm characterised as “hypersensitive transition” into 3 sub-wavelength was observed in glasses with 1mol% and 3mol% of P2O5.
